drivers/iio/proximity/sx9500.c: In function ‘sx9500_buffer_preenable’:
drivers/iio/proximity/sx9500.c:682: warning: ‘ret’ may be used uninitialized in this function
drivers/iio/proximity/sx9500.c: In function ‘sx9500_buffer_predisable’:
drivers/iio/proximity/sx9500.c:706: warning: ‘ret’ may be used uninitialized in this function
